When i am trying to Build my default JavaScript project(BlankApp Apache Cordova) in Visual Studio 2015 preview am getting following error.
The TypeScr
This is a known issue in the CTP3 release. It sounds like you've created a JS-based project, and have not added any TypeScript files, and so of course there are no .ts (aka TypeScript) files passed to the compiler. Ideally the compiler wouldn't be run at all, but the warning is harmless, and everything else should otherwise be working.
